Just googled it and found it listed on the HobbyTron website for $40 with a list price of $65. At the moment, it's listed as out of stock.

What's sad is that boat's list price is less than my first Futaba two channel radio system when I bought it back in 1982. I could buy three of them, at list price, for what I paid for a Futaba 4PLS radio system back in late August from Tower Hobbies
